We stand by the respectful image of John McCain that we used on our cover, and we expect to be judged by it. We were not aware of the manipulated and dishonest images Jill Greenberg had taken until this past Friday.

When we contract with photographers for portraits, we don’t vet them for their politics—instead, we assess their professional track records. We had never worked with Jill Greenberg before (and, obviously, we will not work with her again). Based on the portraits she had done of politicians like Arnold Schwarzenegger and her work for publications like Time, Wired, and Portfolio, we expected her, like the other photographers we work with, to behave professionally.
